Drug info - Xenon and Sulfur hexafluoride

[El Calico Loco]

While looking for information on another anaesthetic (monochloroethane), I happened across some writings suggesting that both Xe and SF6 are inert, non-toxic, and have anaesthetic properties. Wikipedia seems to agree.

Does anyone know more about this than Wikipedia? Do Xe and SF6 have any psychoactive properties, or do they just knock you out?

I imagine Xenon would be too expensive for non-millionaires to use in their research. SF6 looks inexpensive; the problem there might be getting something research-grade, since its primary use seems to be in industrial applications that can tolerate far more impurities than test subjects.
